DMARC.org has published a new overview of the ARC protocol on their website. Download the presentation, or read their announcement. The presentation is released under the Creative Commons license, so readers can feel free to use it when explaining ARC to their colleagues or developing their own materials.
On February 19th representatives from AOL (NYSE:VZ) and Google (NASDAQ:GOOG) successfully tested the first two implementations of the ARC protocol at an interoperability event. LinkedIn (NYSE:LNKD) hosted the in-person, all-day event at their San Francisco offices and facilitated the testing. Also participating were representatives from Cloudmark, Comcast (NASDAQ:CMCSA), DMARC.org, the Trusted Domain Project, and Message Systems/SparkPost.
“We set an aggressive target for testing when we announced the ARC protocol in October. AOL and Google did an outstanding job developing implementations and preparing test systems in time for this event,” said Steven M. Jones, executive director of DMARC.org. ARC addresses a small but important class of messages, like mailing lists and forwarding services, that are impacted when a sending domain has a strong DMARC policy. Jones added, “I think ARC will allow more consumer mailbox providers and other domain operators to join AOL and Yahoo (NASDAQ:YHOO) in adopting such policies in order to better protect their users and their users’ correspondents from fraudulent messages.”
More implementations of ARC are under development, including an open source package that could be used to add ARC capabilities to existing email services. Additional interoperability testing events will be held between now and mid-year. For more information please visit the ARC protocol website at http://arc-spec.org.
The interoperability testing event mentioned when ARC was announced in October (see this press release) has been scheduled for Friday, February 19th, 2016 in San Francisco. Parties implementing the ARC protocol in their product or service by that date should consider participating in the event. Those parties should join the arc-discuss mailing list if they aren’t already on it, and may express interest in the interoperability event there or via this contact form.
What qualifies as “implementing ARC” for this event?
- Writing code (library, milter, MTA) that implements ARC functionality (signing, verifying, etc)
- Building a free/commercial product that includes ARC functionality, whether you wrote the ARC code or not
- Deploying ARC functionality in an intermediary (e.g. MLM) or receiver (e.g. mailbox provider) by the time of this event
If you have further questions, please bring them to the arc-discuss mailing list.
